I.Difference between a rock and a mineral II.Prediction/ Hypothesis-
Minerals
Rocks
crystal
not so much luster
one substance
different colors
more than one substance
We think that the water will evaporate, leaving the crystals from the table salt behind. We also think that the crystals will be in the form of squares and/or rectangles. III.Materials- ·1 piece of masking tape/ duck tape ·1 paper plate ·2 plastic spoons ·5 mixing sticks (2 needed and 3 extra (opt) just in case they are needed) ·2 paper cups ·4 magnifying glasses ·a couple dashes of table salt ·a pot (to boil water in) ·enough water to fill 2 small cups or however many cups there are IV.Procedure- Boil water and pour it into each paper cup which should both be each filled with table salt. Use a mixing stick (1 for each cup) to stir both mixtures until you can no longer see the grains of salt. Then, using the masking/duck tape, tape the two (2) spoons on opposite sides of the plate so that both of the spoons’ handles face/stick outside of the paper plate. After that, you fill only 2/3’s of both spoons with the mixture of boiling water and table salt. Let it sit for at least 24 hours. (To get the best results, let is sit undisturbed) V.Data/Observations- Salt crystals formed in the spoons. They formed in the shape of squares or rectangles. A perfect square actually formed in one of the spoons. VI.C.E.R.- We found out that all of the crystals form in different shapes. Salt happens to form in the shape of a rectangle or a square.
